Cognizant Associate Projects interview questions

Had 2 rounds of interview; Technical round was abt 30-45 mins and 2nd round was taken by a senior employee (M+ level)....This was followed by HR interview....Overall it was a smooth process

I have given 3 rounds interview on same day. first 2 rounds are technical base on Java, J2EE, Spring and JSF. whatever mentioned into CV, interviewer asked all about this things. Interview process was very smooth way. In 1st round asked only Core Java fundamental. In 2nd round asked all framework which i have used into previous organization and some tricky question. In 3rd round, HR describe about cognizant and salary structure. friendly behavior. All process completed between 4 to 5 hours. But offer letter released took lots of times near 6-7 weeks.
